Will Cape Town Run Out of Water?

Available for over a year

9th July - It’s being called Day Zero, the day the taps are turned off in drought stricken Cape Town in South Africa. After 3 years of unexpectedly dry weather leaving no water in the reservoirs that serve the city, we ask what could have been done better to mitigate the water shortage and how to prevent the same thing happening in other cities around the world. Gut Microbiome We are discovering more and more about how connected we are to the microbes that live in our gut. Their impact is not just on our digestive health, but in our brains, on our behaviour and on our immune function. So it stands to reason that we need better ways to monitor our gut microbiome. Roland finds out about a toilet that can monitor your health as you go to the loo, a microbiome grown in a lab and a tiny mini gut on a microchip. Watching a Planet Form With telescopes getting bigger and better at seeing what’s going on in our Universe, what better way to spend your time than watching the chemistry of a planet forming from the dust swirling around a new star? Ideally you need 100’s of millions of years to see the whole process, but the ALMA telescope allows researchers to watch snapshots of hundreds of planets forming at different stages, allowing a picture of planet formation at the molecular, chemical level.
